To easily reproduce data even in variable speed reproduction mode as with normal reproduction mode. Data read from a magnetic tape 1 is supplied to a reproduction equalizing portion 4 through a reproducing amplifier 3. The reproduction equalizing portion 4 trims wave shape and supplies the resultant signal to a data determining comparator 5. The data determining comparator 5 digitizes the input signal. The digitized data is supplied to a reproduction clock extracting portion 7. The reproduction clock extracting portion 7 extracts a reproduction clock. The extracted clock is supplied to a reproduction data strobe portion 6. The reproduction data strobe portion 6 supplies the digitized data to an error correcting portion 8 in synchronization with the reproduction clock. The error correcting portion 8 generates an error correction flag, an interpolation flag, and so forth. A reproduction signal processing portion 10 and a memory 9 process signals and output a sound signal through a D/A converting portion 11.
